4 Claims.
The present invention relates to improvements in devices for manually inserting rivets or the like into work openings, and more particularly to a device for delivering rivets from one end thereof.
The primary object of the invention resides in the provision of a rivet feeding device embodying improved means for releasably holding a plurality of rivets in position to be individually discharged from the delivery end of the device.
Another object of the invention is to provide a rivet feeding device including a barrel adapted to contain a` plurality of axially disposed rivets and means on the delivery end of the barrel which permits the discharge of the innermost rivet and at the same time will grip the next adjacent rivet to preclude its premature discharge from the barrel.
vA further object of the invention is to provide an improved device of the above character in which resilient fingers are employed for retaining the rivets in the barrel and means engaging said fingers for holding them inrivet engaging position to preclude the discharge of the end rivet from the barrel until vsaid device is in the desired position for releasing a rivet.
A still further 4object of the inventionfis to provide an improved device of the character mentioned in which the barrel and a thrust member or nose piece engageable with the Work are relatively movable for permitting the resilient fingers to spread, and in which the thrust member is of a form such that it is not likely to cause marring of the work.
Other objects and advantages more or less ancillary to the foregoing reside in the specific construction and aggroupment of the elements peculiar to this structure, as will become apparent from a more complete examination of this specication.

Fig. 8 is a View similar to Fig. 6 showing the corresponding parts employed in the Fig. 5 modification, and
Fig. 9 is an end view of the Fig. 8 construction with a confining tubular member in flnger restraining position. Y
Referring to the drawings for a more detailed description thereof, and particularly Figs. 1 to 4, inclusive; which illustrate one embodiment of the invention, the improved rivet feeding or placing device is generally` designated by the reference numeral I 0 and includes a barrel II which forms a support or magazine adapted to contain a plurality of rivets I2 or other articles to be fed.V The barrel I-I is open at both ends thereof and is fabricated with a longitudinal slot I3 in the wall thereof. A plunger I4 is adapted to be inserted Vthrough the open outer end I5 of the barrel for engagement with the outer end of a series of rivets previously placed in the tube asl shown in Fig.. 4, said plunger being formed Vwith a lug I6 which projects through the slot I3 and is movable therealong.l A tension spring I1 is connected to the lug I6 as indicated at I8 and constantly applies a pullingforce to the plunger I4, causing the latter to advance the rivets I2 valong the barrel I`I toward the inner or delivery end IIthereof. j Y
Soldered or otherwise iixedly mounted on the inner or delivery. endV II' of the barrel II is a bracket I9, which includesa sleeve portion 2D surrounding or partially surrounding the barrel and a pair of spaced ears B projecting substantially radially ofthe barrel. The ears B form a support for an elongated substantially U-shaped cover 2|V which is adapted to-be releasably held in closed position adjacent the barrel II by a spring clip 22 which is carried by the cover and engageable with the barrel adjacent its outer end. The cover 2l' is pivotally connected to the ears B by means of a transverse pin 23 which permits the cover to be swung toward or away from the barrel II during the loading of the barrel with rivets or the like. Between the ears B there is provided a grooved roller 24 which is rotatably mounted on the pivot pin 23 and around which extends-the tension spring Il, said tension spring extending longitudinally within the cover 2| and having its outer end suitably anchored thereto by means of a lug'or theflike 25.
A sleeve 25 is permanently secured to the inner or delivery end II' of the barrel IIl said sleeve being formed with a plurality of resilient lingers 21 adapted to be urged into clamping engage-k ment with the innermost rivet supported within the barrel The inner or free ends 28 of the resilient iingers 21 are convexed and normally ex outwardly away from the axis of the barrel and unless restrained would permit uninterrupted discharge of the rivets from the barrel. The confining or restraining means for the fingers comprises a tbular member 29which surrounds the sleeve 26 and fingers 21 and is axially movable relative toy the barrel The outer endof the member 29 is formed with a lug 3| which is disposed within the slot |3 for preventing rota# tion of said member relative to .theb'arrel Thenormal position of the member 29 is shown in Figs. 1 and 2 of the drawings, and it will `ber noted that the innermost end ofsaid Ymember has bearing engagement with the iinger ends 28 so as to urge said ends inwardly for clamping engagement with the head of the innermost rivet v 3|). r'Viliiile the 'normal tendency of the spring lingers 21 is lt0 'eX outwardly, the tube `2S brings suiiicient pressure to bear on the linger ends to c'au'se the latter to `rmly grip the innermost rivet head and thereby preclude its discharge from the barrel However, as will hereinafter appeanjthe barrel and sleeve v2t are moved longitudinally relative to the 'member 29 to free the ends 28 from said member whereupon 'they eX- pan'd and fallow the innermost rivet to be ejected. A' V`In addition ti the series of lingers A21, the sleeve 26 salso forinefd with a pair o'f diametricallyopposed resilient fingers 32 which are shorter than the prigersi. The iingeis 32 lare adapted to ex- 'tend through oia'fnetiieaily opposed slots 33 formed iii the vdelivery end 'of the barrel n and Yfunction'tm prevent the escape of the rivet next adjacent the innermost rivet being ejected, As sh'o'wn in Fig. 4 of the `drawin`g's,Y the innermost rivetw has just been reieased from Athe fingers l21 and' has entered the opening 34 within the work 3,5 and simultaneously with the release of the iiyet, the fingere 32 are urged 'inwardly by the tnbul'armember 29 for engagement with the head ofrtiiejnext adjacent rivet 36. 'The fingers 32 are simiiarin eonstruetion tothe engere 21 m that they' nfo'rinailyffiex joutwardlyaway from the axis oi the barrel VV|'|. In Jor'derto 'urge the short v1ing-erefz intojeiamping engagement with the head oi the 'rivet '36, the end ofthe tubu1ar member 29 is formed with diametrically opposed downwardly extending lips 31Awhich are positioned directly above the fingers 82. When the tubular member 29 is inthe position shown in Fig.A 2 of the drawings, jth'e lips -3| are out of .bearing engagement with-the lingers '32, and said lingers are thereby free to flex outwardly Y'away lfrom the rivets. As before indicated, at that ltime the fingers 28 are urged into gripping engagement Ywith the head of the innermost ri'vetm30. However, as ythe Abarrel m 'moved longitud-iii -iiy relative te the jtiibuiar o'n shown in Fig. 4 o-'f the member/29 tothe po' I drawings, the "lips `81 l bearafgainst the fingers 3.2 to Atir-ge said angers inwardiy :for gripping the li'e'ad o'f'the lnextfadjaeehtrivet `3'6. 'This action is f'sirnltaneou's with the `release of the innermost rivet 30, 'and it will be seen that -only yone rivet ata itilmf'e fis thereby permitted to T'be freed `from th' fdlve'y end Loffjthe itu-be.
`on the work surface.
rivet is being ejected and said spring functions to return the barrel and bracket to normal position when the device is removed from the work 35.
A pair of arms 39 are secured to andextend forwardly of the tubular member 29 and are adapted to engage the surface of the work for holding the free ends of the resilient lingers 21 in spaced `relation to the work; Thus the resilient Vhgers are free 'to flex outwardly as the tube is moved toward the work without scraping The arms 39 are formed with laterally extending feet which engage the surface of the Work without marring or otherwise damagingtne same. n
f It will loe-seen Vfrom the foregoing description that when the Abarrel has been charged with aseries of rivets 2 and they are subjected to feeding pressure by the plunger |4, the head of theinnermost rivet 30 will be engaged by the inwardly pressed ends of the resilient'iingers 21, and said rri've't will be held with the stem-thereof Varojecting from 'the tip of 'the device ready to be inserted into the opening :34 of the work 35, as shown in Fig. 2. When inserting the stem of the rivet 30 into the opening 34, the feet 40 will be brought into bearing engagement with vthe surface of the work 35; whereupon 'the barrel is shifted toward the workjby sliding movement withinthe 'tubular member 29, moving the ends 28 ofthe iingers A2'1 out of engagement with the 'tubular member 29 and'simultaneously causing4 the lips 43"! to depress vtl'ie'iingers 32. As 'the ends 2'8 are released from the tubular member 29, the 'iingers 21 will flexv outwardly 'and the rivet 30'vin'11 be projected or snapped 'into the work 'opening by 'the actionjo'f the spring VI1. Thereupon, the barrel H is released, and under the action of the urging those Ifingers inwardly. :In this form the Y .A "c'oil spring 38 is interposed between the bra'ket sleeve l2f0faf-1d "the louter end of the tubular -Tmenber v12,59.- The bracket |9 'being xedly secured to the barrel |i| vvillimove with said barrel agamstjiiie f resistance 'for the spring s s, *white a is repeated all of the rivets havefbeenexhaust'ed from the barrel and when it is desired to reload the barrel with fan Aadditional supply of rivets, the plunger |f4 is removed through lthe open end I5 by stretching the spring |`f| .and after loading", Vthe plungerfisagain positioned in abutting'relation with' the-header the end rivet.
The. 'form or the invention shown in Fig. 5 diners :from the previously described form by omitting the '.p'air fofwshort .lingers and vthe 'elepressing lips formed on theftubularimember-for construction jof the barrel |f|., `.plunger |'4 A'and spring-l1 is] the `lsame as the preferred form. A sleeve |f2-6 uis lpermanently securedto the .inner or delivery endY of the barrel-H l"and said :sleeve is formed with a plurality of resilient iingers`r|2 having `convexed ends :|28 adapted ,tor beurged intol clamping engagement with -the innermost rivetlf.. Ihe ends |28 are-urged inwardly into rivet clamping engagement by the tubular mem- 'bei' |29 which is .mounted on the bar-rel H in ringer surrounding position and is slidable relative to said barrel. By shifting the .barrel troward the work |35., the ends '|23' will be' free to flex outwardly .'t'o release 'the innermostrivet '|30 into the 'opening 134, As the device is moved away `from the Avvo'rl; |35., the 'iingers .are urged inwardly by coi'ila't fw'ith the fmeniber |29 to clamp the nextradj'acent rivet |36. "VItwill :thus be `'seen that the Yoi 'the two-forms is simi.,
lar insofar as restraining the innermost rivet is concerned butthat the modified form dispenses with the means for preventing escape of the rivet next adjacent to the innermost rivet.
Although the foregoing description is necessarily of a detailed character, in order to completely set forth the invention, it is to be understood that the specific terminology is not intended to be restrictive or confining and it is to be further understood that various rearrangements of parts and modications of structural detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.
